State the functions of the liver

  

Answers


Isacko
i. Excretion

in this function the liver is aided by the kidney

deamination i.e. excess amino acids converted into urea and uric acid which is transported to skin and kidney for removal

detoxi?cation where harmful substances are converted into harmless ones in the liver and transported to kidneys for removal

breakdown of worn out blood cells and haemoglobin and the residue excreted through the
kidney to give urine a yellow tinge

Breakdown of sex hormones after they have performed their function and the wasted are
released through the kidney and bile.

ii) Homeostasis

regulation of blood glucose

the normal amount of glucose in blood is about 90mg/ 100

increase in blood sugar is detected by cells of the pancreas which secrete insulin

insulin stimulates the liver to convert excess glucose to glycogen

further excess glucose is converted to fats until the normal blood sugar level is attained

Excess glucose is oxidized to carbon IV oxide, water and energy. Excess glucose is also used in respiration

decrease in blood sugar level below normal level is detected by the pancreas, which secretes glucagon which stimulates the liver to convert glycogen to glucose until the normal sugar level is attained

fats, amino acids are converted to glucose

it also leads to reduced oxidation of glucose

Deamination

excess amino acids are deaminated by the removal of amino group

the amino group is converted to ammonia

ammonia combines with carbon IV oxide to form urea

urea is excreted in urine through the kidney

Detoxification

poisonous substances are converted to less harmful compounds

Thermal regulation

maintenance of body temperature

heat is generated in the liver by chemical activities

the heat is distributed
